DDM 2909 Automatic Density Meter by Rudolph Research Analytical

The Rudolph DDM 2909 Automatic Density Meter features built-in Peltier Temperature Control of the Sample, Full Range Viscosity Correction, Reference Oscillator and VideoViewTM for easy bubble detection, and is fully GMP/GLP Compliant. With the flexibility of Windows the DDM 2909 is Network ready with Internet connectivity allowing remote access to Rudolph Research Analytical’s Service and Technical Support Team.

The 2909 comes complete with 20 Density to concentration tables which include Brix, Alcohol, API, and many various laboratory reagents. An unlimited number of additional tables, polynomials, and formulas may be added.

Flexible Method Management

Factory installed density meter measurement methods allow for immediate selection of the correct method to match the most common applications.

For unique Density Meter measurement applications, create a sample method using Concentration Tables, Formulas, and Polynomials to match the density measurement methods used in your laboratory. Just a few of the many possible customized sample methods shown below:

Baumé of Hydrochloric Acid

Normality of Sulfuric Acid

Density of Gases and Aerosols

Drug to Propellant Ratio

Lead Content

ppm Gold in Acid

% Toluene in Heptane

Fat in Lubricant

Mole Fraction of Methanol

% HNO3

Monomer Solutions

Potassium Permanganate

Hydrogen Peroxide

Molar Solutions of EDTA

SG of Urine

Sweeteners

Sodium Hydroxide

Setting up your custom method on your Density Meter is as simple as filling out a few screens like the one below:

Full Feature VideoView™

VideoView™ provides superior high resolution visual bubble detection within your samples with live on-screen video viewing. Rudolph’s industry leading 10X magnification aids in identifying bubbles if present in the sample.

The video clarity, magnification, and resolution mean no more straining to see small difficult-to-detect air bubbles in your sample. Rudolph’s exclusive VideoView™ is protected under Patent #7,437,909.

Oscillating U-Tube with Viscosity Correction and Reference Oscillator

The DDM 2909 Density Meter’s oscillating U-tube with full range viscosity correction and reference oscillator allows long term calibration stability and measurement at all temperatures with a single calibration.

Computer Windows Based Flexibility

32 gigabytes of internal Compact Flash Memory .

The DDM 2909 Density Meter is network ready and data may also be saved directly to your server or to any directory desired.
